2.2 Ozone Research: The Dobson Unit

The Dobson Unit is the most common unit used in ozone research to identify the “thickness” of the ozone layer and is named after scientist GMB Dobson.

The thickness of the ozone layer is expressed in Dobson Units (DUs), as it converts what the “physical” thickness of the ozone layer which would equal the thickness of a dime if it were compressed to one atmosphere pressure at 0°C.
